Under Win 7 I created a new 100 GB disk partition (L:) to install Ubuntu 12.04. I then rebooted from the Ubuntu install CD, selected "Install side by side" and now I'm stuck. I end up at the Advanced Partitioning Tool and I do not know how to tell the installer to use the L: partition. Any help would be appreciated. Thanks!
Thank you. I have successfully installed Ubuntu 12.04 alongside Win 7. However, now when I reboot the laptop it goes directly to Win 7 with no option to choose Ubuntu. Any thoughts on how to get the boot-time choice to show up? Thanks!
I used to dual boot. But when one OS had a problem, the only way to fix it was reinstalling BOTH operating systems. I also had problems dual booting with Fedora. Now I use VirtualBox and run virtual instances of operating systems instead. If one of the virtual OS's dies, I just delete it and create a new one.
New installations of recent versions of Ubuntu does not use a separate swap partition any more. They use a swap file by default.
Boot windows and delete the 100GB partition (L:) and try again. Ubuntu needs to create at least two partitions, "/" in ext4 format and "swap" in it's own format in place of (L:) during installation. It will find the unused space and do what is needed.
You can also choose "Something else" during installation and manually create these partitions. The swap partition is needed for virtual memory management and can be 2GB-4GB in size.
